Product overview
ZMRN1016S3-V5 consolidates cabinet inputs and relay circuits for networked equipment operation and status management.
Functions and integration
Relay contacts
NC, COM and NO terminals support normally closed or open control circuits; contacts do not provide load power.
Inputs
Eight inputs connect compatible field signals for monitoring and control logic.
Output modes
Switch, pulse, interlock and toggle modes cover different operating behaviors.
Management
Mobile, Web and PC tools provide naming and schedules; RS485 access follows its device protocol.
Applications and operating workflow
Cabinets
Centralize equipment switching and field input states.
Lighting and auxiliaries
Name channels by load and combine weekly schedules with local operation.

Selection and system combinations
Select by channels and operating modes when Ethernet control and input status are required together. Compare dedicated input modules for many contacts and Q-series controllers for other output scales.
ZMRN Q Series Network Relay Controller
Select a Q-series configuration by circuit count, load type and site network. Compare 4G models for cellular access and the high-power range for higher-load circuit control.

01
Build a circuit register around eight inputs and outputs
Eight relay outputs and eight inputs consolidate circuit commands and field states in one cabinet. Map channels to lighting, contactor coils, equipment commands and feedback. Align custom device and channel names with cabinet labels for operation, schedules and maintenance. Allow for insulated mounting, terminal access and Ethernet routing, with the DC12V controller supply planned separately from load power.
02
Use NC, COM and NO for the required contact relationship
Each relay exposes normally closed, common and normally open contacts. Use COM with NO or NC according to the circuit function; the load receives power from its own supply. Inputs accept compatible buttons or feedback. Linking each output purpose to the associated input state helps distinguish the command, relay state and external equipment response in centralized operation.
03
Match output behavior and weekly schedules to the task
Maintained switching suits continuous ON/OFF, pulse suits a short start or reset, toggle suits a single-button change, and interlock supports grouped selections. Assign modes by channel purpose and combine them with weekday and time arrangements. Consistent device names and channel lists across mobile, Web and PC access support shift-based operation and temporary changes alongside recurring schedules.
Selection questions
How should a cabinet allow for board wiring and maintenance?
Plan routes for DC12V power, Ethernet, relay terminals and input terminals, with reliable mounting and insulation. Preserve access for cable connection and terminal work.
How can commands be distinguished from equipment feedback?
The output represents a switching request or relay state. An associated input can carry equipment feedback, linked through the channel names and circuit register for operating review.
Frequently asked questions
Do contacts power the load?
No. Design load power separately from the relay switching contacts.
Can QC8 ratings be applied?
No. These are different products with separate electrical specifications.
